Good

• example 👍

Bad

• priority 😕

fastify support application/json and text/plain but we can add it by addContentTypeParser

refs

• https://www.fastify.io/docs/latest/ContentTypeParser/

is a fundamental feature of fastify -> encapsulation context, it control decorators, hooks, plugin, route

refs

• click

decorators API allows customization of the core Fastify objects e.g. server instance , any request, reply objects

this might be useful for what we do in express such as Reflect req

• extends and reuse custom functionalities

• plugin can be whatever e.g. routes, decorators

• fastify(3.x) not support middleware by default
• not recommended to use this

• like morgan but better with pino

• fastify tries to catch as many uncaught errors as it can without hindering performance

app.get("/", () => {
  throw new Error("error");
}); // -> catch and if `throw new Error` default is status 500, internal error

also can write a custom hook for catch error

• fast allow user to eject each hook starting incoming request e.g. onRequest

• Fastify uses a schema-based approach
